How much will that barrier cost? You have a temporary injunction and the permanent injunction matter is yet to be heard. Imposing a significant cost to the defendant before the trial on the permanent injunction is probably not something the court will be willing to require for what amounted to a brief violation of the order. After all, if you lose the permanent injunction then the defendant's expense on the barrier is wasted. You can make the motion, of course, all I'm saying is don't get your hopes up too high on this if the barrier you seek will be costly to install.The word may have filtered down the grapevine as the trucks have now stopped.
I'm going to file the motion for contempt and to have the original preliminary injunction modified to require the defendant to install a physical barrier.
